Yes I currently have an SD car in the reader but it does not pick it up in order to try to flash it automatically with the .d7. I'm trying to get the pins shorted but it seems it just continues in the process and repeats might need to try something else to short them.

@geekonocito Your SD card is showing up, is it 256MB or 256GB? What format file system did you use? If it is 256GB I doubt that is gona work with the iDrac.

Its currently a 2gb card partition down to 256mb in FAT with the .d7 in the root of the card. it actually shows up in the boot process.( see below) if I am correct. Was there something needs to be done in order to get it try to flash i thought the process would see the file and then do this automatically.

@geekonocito Hum, ok, what tools are you using to partition and fat format that? It sees the raw device, but it doesnt look like it is finding a file system or the firmimg.d7 file. And if the sd card is what an idrac expects it is fully automatic, if any little detail is off it does nothing.

@rgrimes Currently just using windows in order to format and resize the SD card, nothing really special there I thought to be able to do. Is there a better way?

I am using Dell Latitude E5550. I received a message to update the system BIOS. I update my system BIOS. After installation, I am facing a black screen when I used a chrome browser to read a blog page like best canoe reviews etc. tell me how can I solve this problem.

I'm also facing same problem on a R320, my problem is to get recovery mode ... the image is enough good to start kernel (crap!). Here's my actual default log :

So I cannot get recovery mode ... idrac7=>

Any ideas ?

Tue Aug 10, 2021 4:42 pm

@darkspeed I do not know why you shorted the CMD to GND, that is NOT how you get an iDrac7> prompt. There is a set of test pads that you need to place a jumper of DBG to enable the access to u-boot and idrac7 serial console. Also if your iDrac is flashed with very recent code even that wont work, as Dell has disabled this access because of the idracula vulnerability.

@rgrime .

Hello,

I've tried to found a solution to be in recovery shortcut on CMD/GND leads to emmc unreadable, i had hope that I will force to be on recovery on emmc error :-( Off course, emmc Works as before without shortcut.

where is located the debug jumper ?

Perhaps I could flash the SPI (with Eeprom burner) to get Uboot on a older version ?

which version is suitable for recovery ?

Regards

@darkspeed I do NOT suggest an attempt to flash the SPI with an eprom programmer. FIRST you must get the DBG jumper set. Please read the thread, the details are in there about it. You are correct that shorting CMD to gnd well cause the eMMC to fail, but the default action on that failure is to halt the CPU, so does you no good at all. I believe with the DBG jumper installed AND CMD shorted to ground your probably going to end at a u-boot prompt, but not certain.

Is there any way to control the fans just from the IDRAC console? When I hookup using UART I do not get a Linux shell but just an iDRAC7=> prompt (I think my system is super hosed):

Is there any way to control the fans just from the IDRAC console? When I hookup using UART I do not get a Linux shell but just an iDRAC7=> prompt (I think my system is super hosed):

I've given up on trying to recover this system but I would like to be able to control the fans

answering my own question -- this works:

iDRAC7=> util fan -set all low

for a list of all commands run "util":

next question that i hope someone may have the answer to: is there any way to monitor temperatures from idrac console? can Windows access temperatures when the idrac is dead?

Does anyone has a backup from an old SPI Boot rom in R320 (who can be interrupted with jumper, not as latest versions...) ?

I'm stuck with latest version of bootloader, after dd with zero the emmc ... no rescue, only PANIC :-(

(I had a backup of my Emmc and it works if I put back my backup)

Regards

Nicolas F.

Hi. I have one from a R720. I don't know if the boot loader is the same.
